6.26.13 Abnormal speed detection
H
: Abnormal speed detection time
H
: Overspeed detection frequency upper band
H
: Overspeed detection frequency lower band
• Function
For V/f control (
R V
:
,
,
), it always monitors the estimated speed of the motor, even when the motor is
at rest, and if the speed remains out of the specified limits for the specified length of time, it outputs an
error signal.
For sensor speed control (
R V
:
,
,
,
,
), it always monitors the rotational speed of the motor, even
when the motor is at rest, and if the speed remains out of the specified limits for the specified length of
time, it outputs an error signal.

H
: Undervoltage detection level
H
: Undervoltage trip selection
• Function
This parameter is used for selecting the control mode when an undervoltage is detected. (Invalid, while the
inverter stops.)
H
=
: (Disabled) ··············· Inverter stops,but does not trip. (FL is not active.)
H
=
: (Enabled) ················ Inverter stops and is tripped because an undervoltage is detected. (FL is active.)
